Hi Pentimento, I thought of a few more portrayals of famous people on the big screen & these came to mind. 3 different actors playing Andy Warhol:Guy Pearce- FACTORY GIRLJared Harris- I SHOT ANDY WARHOLDavid Bowie-BASQUAIT

Also Sienna Miller played Edie Sedgwick (Warhols mid '60's Superstar) in FACTORY GIRL.Lili Taylor played Valerie Solanas ( who wrote the S.C.U.M Manifesto feminist rant), in I SHOT ANDY WARHOL. and Jeffery Wright played Jean-Michel Basquiat (Andy Warhol mentored him through the '80 & he became huge in the downtown NYC art scene.) in BASQUAIT.
